Document Type and Number:
WIPO Patent Application WO/2022/075396
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a compound which is suitable for a low refractive index layer in a capping layer in order to improve the light extraction efficiency of an organic EL element. [Solution] The present invention is achieved by focusing on the fact that a thin film of an adamantane compound has excellent stability and founding out that an amide compound, ester compound, amine compound or ether compound, in the center of which adamantane is arranged, exhibits low refractive index characteristics; and an organic EL element having excellent luminous efficiency is achieved by using this compound as a material which constitutes a capping layer that has a low refractive index.
